This price action reinforces the fact that wise Risk Management is at the core of profitable futures trading over time. The double-edged sword of leverage at it again. With oil all over the map, so are trading policies, which can increase the challenges when they are introduced with no warning, including in the middle of a trading session. I know at least one broker today suddenly disallowed trading in both CL and QM except for closing out positions, and any extant positions were subject to liquidation! Previous to that they had required CME margin for day trading. I have also heard of at least one requiring 150% of CME margin to be able to day trade oil. It would be interesting to hear what futures traders on here are hearing from their brokers/FCMs. Including IB, with that major 88 million loss.
